Run NiosII program in command line + hostfs

Hello,

I'm running a program in NiosII that read and write files in my host PC. For that I'm using the NIOSII IDE.

As I have to repeat this running several times, i'd like to make this run full automatic so I don't need to enter in the graphical mode every time.

For that i'm having a problem in trying to run niosII program because using the command line, i'm not being able to mount the hostFS. Does anybody know how can I do that?

So far, my script to program FPGA + run NIOSII project has the following steps:

1- Program FPGA

>> quartus_pgm -c "<usb-blaster name>" <file.cdf>

2- Build nios project:

>> nios2-build-project --projectName=<projectName>

3- Configure Nios

>> nios2-configure-sof <sof_file.sof> && nios2-download -g <file.elf>

4.1- Open Nios terminal to check output of running program (in one linux terminal)

>> nios2-terminal

4.2- Run program in Debug mode (required for hostFS to work) -- in another linux terminal

>> nios2-debug <file.elf>

Once again, following this steps I cannot access the file to read and write because I think hostFS is not mounted on /mnt/host

Using IDE the program works fine.

I'm using quartus + Nios2-IDE version 10.1

regards,
